On our selfhosted github actions runners, the action fails because we have /tmp mounted noexec, a security requirement.
To use rustup manually on the instance, we could use the TMPDIR env var to define an alternative temporary directory
TMPDIR=/opt/tmp rustup.sh
On a runner, there's an env var RUNNER_TEMP that is a temporary directory for this run. In workflow example, I show how we use this to work around our noexec setting on tmp.
It would be great if the workflow could just use RUNNER_TEMP by default. Setting the environment variable TMPDIR equal to RUNNER_TEMP should be enough to make this work automatically.
Workflow example
jobs:
tests:
name: Lint and test
runs-on: [self-hosted]
steps:
- name: Check out the repository
uses: actions/checkout@v3.0.2
- name: Setup rust
uses: actions-rs/toolchain@v1
env:
TMPDIR: ${{ runner.temp }}
